i SPECIFICATION forming part of Letters Patent No. 705,821, dated July 29, 1902.

llpplicationflled Mar-ch 22,1902. Serial No. 99,395. (No model.)

` and DANAl L. CHnsTnRMN,"citizens of the UnitedStates, residing in the city and county of Philadelphia, State of Pennsylvania, have invented new and useful Improvements in Trusses, of whichthe following is a specification.

Our invention consists of a truss whose pad is adapted for rights or lefts, and in which the adjusting-screws and sharp edges are `removed from contact with the body of the wearer.

Figure l represents a perspective View of a portion of a truss embodying our invention, the pad being adapted for the right side of the body. Fig. 2 represents a perspective View of a portion of the truss, showing the pad removed to the left.` j Fig. 3 represents alongitudinal section ot' a portion on line ac Fig. 1. Fig. 4 represents a transverse section on line y y, Fig. 1. Fig. 5 represents a transverse section online e' 2, Fig. 1.

Similar lettersof Arcaferen'ice indicate corresponding parts in the figures.

Referring to the drawings, A designates the spring or body-baudet a truss, andB designates the pad thereof.

O designates a curved or segmental plate, the opposite ends of which have longitudinally-extending curved slots D D therein, and E E F F designate screws which are passed, respectively, through said slots, the screws E E entering the pad B and the screws F F' entering the spring A, thus connecting said pad and spring, the slots permitting the longitudinal movement of the plate, spring, and pad on each other, and thus providing for the careful adjustment of the pad, it being also noticed that the slots are matched.

It will be seenthat the plate O curves downwardly from the end of the spring A, and so places the pad in position for proper application to the body. It will also be seen that the shanks of the screws E and F are of less diameter than the dimensions of the slots D and D in the direction ot' their width, by which provision spaces G exist between said .li screws and the adjacent walls of the slots, so as to permit the plate C to turn laterally to a certain extent on the screw F at one end and the screw E at the other end, and thus change the position of the pad B, as shown in dotted lines, for purposes of adjustment in the direction' shown in said dotted lines, the screws being afterward tightened to retain the plate in its adjustment. adjustment the several screws are tightened, and thus the plate retains its adjusted position. Furthermore, the plate may be removed from the spring A and the latter reversed and said plate again secured to said spring in downwardly-curved direction, by which provision, as the slots D are matched, the pad occupying a position at the right side of the body of the wearer, as in Fig. l, may be disposed for service at the left side, as in Fig. 2. Again, the screws are on the outside of the pad and the spring, and no objectionable surfacesor edges are presented to the body of the wearer.

H designates a stay on the inner side ofthe spring for receiving the ends of the screws F F and strengthening said end.

It will of course be understood that a strap may be suitably secured to the spring A for holding the truss in position and that the screws may be provided with stud-heads for the attachment of said strap therewith.

Having thus described our invention, what we claim as new, and desire to secure by Let ters Patent, is

l.' In a truss, a pad, a spring, and a downwardly-deflected plate adapted to connect lsaid pad with said spring, the opposite end portions of said plate having matched slots therein for the connecting members of said plate and pad in either the right or the left disposed position of said plate, substantially as described.

2. In a trussta curved plate adapted to connect the pad and spring of the truss, opposite end portions of said plate having curved matched slots therein for the' connectingscrews of said pad, substantially as described.

3. In a truss, a pad, a spring and a curved After the plate adapted to connect said pad with said plate in both longitudinal and lateral direcspring, the opposite end portions of said plate tions, substantially as described.

having matched curved slots therein for the JOHN H. CHESTERMAN. connecting-screws of said plate and pad in DANA L. CHESTERMAN. either the right or left disposed position of Witnesses:

said plate, said slots and the shanks of said JOHN A. WIEDERSHEIM,

screws admitting of the adjustment of said l WM. C. WIEDERSHEIM.
